Searching is not a problem. The problem is that 90% of search results are worthless, because all links in old posts are missing.
There are no capx examples, no links to plugins, no screenshots, nothing!
The entire subforums ("Completed Addons", "Effects", "Tools and Resources") are now basically useless because links in posts are lost.
I know you wrote that formatting in old posts will be fixed, but could you please confirm that the missing links in posts will be restored as well?
If not, you need to find the way to somehow make the archive of the old scirra.com forum accessible.
