This is done now. I've also updated a bunch of stickies with new information. Let me know if there's any other changes you think should happen.
I like the new changes; however, a small issue.
How is "WIP Addons" a SUBforum of "COMPLETED addons"? A little contradictory, if you ask me
My suggestion: Rename "Completed Addons" to "Construct Addons"
EDIT: Also, while there may not be enough of either to really need this, consider splitting Plugins and Effects to make Addon browsing easier (I think that, for now, the thread title method is fine though).
