Great research. :-)
I will work on this tomorrow (if I got some time) and add it to the default list of supported engines if you don't mind.
I am almost done with this engine. Though it is not really worth the work (except for me optimizing the system as this one had a lot strange things in it).
All links are only visible for members only except blogs who are tagged as "visible to world". And not much allowed this so far.
OK I think I got it all right. Next version has this as default. Thanks for all the work Ozz!
yes the "extra submission" will be a new option soon...so people stop arguing about "why elgg or wiki is not posting my article but just a link on user page".
I prefer not to post articles there but many ppl want it.
