The Quote System
I'm not sure if anything can be done about this since it seems to be a core element of the software itself, but as it stands it is horrendously difficult to use when replying to a thread that involves multiple discussants. As it stands, either you're going to have people serial posting as a means of replying to all the little tid-bits in the previous replies, or people just aren't going to use it.
Motion Sickness when Typing
It might only impact (fast?) touch typists, but when you're typing in a reply the screen dances all over the place. It is actually quite nauseating and I don't actually get motion sickness. Having a fixed box ala the majority of free BBS would certainly help usability. IMO, of course, but then again I type at 130 wpm (and have the typographics to match! )
At the moment, almost every action requires that you use the mouse to put in smilies, adding formatting, etc. Even when you do have the ability to use the keyboard (Ctrl-I for italicised text, etc.) it requires that you highlight the text and then add text. I'm not sure whether this is a problem with the FCKeditor in general, or whether it is peculiar to this forum.
Once again, it might just be my own little hurdle that I have to get over, but I would rather have UBBcode or the equivalent. Typing in an extra few characters is less invasive (to me!) than having to stop, highlight the text, and then either press Ctrl-I or move the mouse and point and click "I" just to get some italicised text.
I strangely find it easier to strip away the FCKeditor and just code HTML. For those that didn't know that you could do that, just press Control, keep it pressed, and then hit the Tab button once. Of course, if you do that then you're going to have to type in HTML code, but that might even give you a few more options. Well, unless that particular code has been stripped away by the software, which is eminently reasonable. (It certainly helped in allowing me access to the endash in the following comment, as well as completely removing the motion sickness glitch, since the page isn't always bouncing around.)
The Wandering "Edit" Button
This keeps on disappearing, which is frustrating when coupled with people getting used to the new formatting options, and the new – forgive me – terrible quotation system.
I can understand the desire to push the product range, but community does have a more expansive meaning on the current web. Users are just expecting more from their web time, whether it is personalised avatars, the ability to put in more information to their profile, or the ability to select a game (for example) that lies outside of the FFG range. Not a great push mechanism, for sure, but more client oriented than company oriented. Makes people feel a bit more special, rather than as a potential punter. (Admittedly, you are providing them a place to chat, but a "community" is that much more than a BBS, despite phpBB's tagline.)
Leave Old Forum
I definitely agree with this one. Just throw it as old.fantasyflightgames.com/gobbledegook_url and remove the ability for people to post to it. It might take up server space, but surely not that much. Surely? (I might be surprised, but given the amount of posts on the old boards, I would be very surprised if this was a particular load on the server.
Just some comments that might help to improve the overall site. In general, though, I think that it is a much improved interface and kudos to the designers.
