Great, that is what I thought. Thank you for your solution and thank you for picking-up this great add-on again :-)

If you will got some sparetime i have something to think of. I suggest that moderator or owner (if permission is granted) will be able to delete desired part of history of the post. Those kinds like grammar edit etc. .-)

Also short description option for post history version will just do fine .-)

Also I have suggestion for colaborative use of it in the thread. After first post there can be second post (produced automatically and simultaneosly with first post) dedicated to colaborative answer with history option - editable by anybody. Then from 3rd post discussion may start. Anybody willing to contribute to colaborative solution in the second post will be welcomed .-)
Second post - if empty yet should be rolled up - saving some space....

Thank you!
