Well I am loosing track of the edits, myself.
Even though they appear as well founded and needed.
You must have some methodical process you are using.
basically going from the top pages and working my way down. Fixing everything as i come to it. Reviewing all of the random bug reports and fixing the issues if they have not already been fixed. Adding the forum features that are of bare minimum for all large forums in 2015.
Over 750 files are being touched in some manner. Its a task thats been neglected for several years of the UBB.threads v7.x series.
v7.6.0 will be the base reason for current UBB.threads forum operators to upgrade.
