I've noticed that more than one person can be editing the Wiki post. If you save your edits first, when the second person saves their edits, your edits will be lost, as the second person edited from the original Wiki. So, how about programming a 'lockout' into the code so that if someone is alredy editing the Wiki, a second person can't edit it until the first person saves their edits.

that's what the revision button is for. its not erased for good, but becomes a previous edit.

So exactly how does the revision button work? Do you use it after an edit when you see someone else edite and your edits are 'lost'?

If it appears your edit is lost, click revision. You will see all of the revisions. You can copy paste yours and re-add it to the wikipost.

This is an "edit conflict".

Locking out all other people is potentially problematic and open to abuse. One alternative would be to mimic Wikipedia: record when someone starts editing, and before saving their edit check to see if any revisions have occured since they started editing. If so, notify them of the edit conflict and prompt them to merge the edits (show them the new version as well as the one they are trying to save).
