I'm volunteering to assist in maintaining the Ruby mediawiki API gem, as it's fallen into a near abandoned state.
This left it locking to dependencies that were so old, it was a poison pill to projects, further lowering its usage.
In addition there are numerous improvements that could be made (top of mind is better cmcontinue handling...)
Attached LFaraone as we've previously worked together and (I think?) would vouch for me
