Hmmm... I thought some designers would have offered opinions on this by now.
Right now, the MG logo at the very top points to the Forum home. Change that to point to megaglest.org
The text link on the forum navigation bar could be changed from "home" to "Forum home" but that's a bit wordy. Perhaps a graphic representing a forum or bulletin board could be place somewhere near the main MG logo at the top, and the text link for "Home" could be replaced with "Forum" and an additional text link next to it, "megaglest.org"
On the footer of each page, I was thinking text links pointing to the forum home, the MG home, and maybe the wiki, etc.
For the wiki? something similiar xD.
By the way, any agreed changes are something I could likely implement. It's been a while, but I'm sure I could figure it out. I remember something about editing php templates for bulletin boards, though I primarily administered phpBB
installations. I've never administered a wiki.
