#3,
here we go:

after checking several wikis, I'm about to migrate all data to wetpaint, but djeeezes, there are some annoying formatting bugs (bold text, deleting open lines, centering issues) and they're apparently not able to get them under control, and I haven't found a way to edit (and save) the code. PBwiki for instance, offers the ability to use the interface or you can choose to edit the code directly. Perfect. (But they don't have discussion forums in the wikis.... too bad).

Would be great to put this in your matrix / wizard: the ability to tweek the system via the source code.

thanks
