UBB.threads PHP Forum Software Community Forums UBB.threads Version 7/8 Support Limit the Max size of a PM? (version 7.1.1)

My current limit is set to 100 and I will be dropping it to 50. I'm more wondering if there can be a limit placed on the actual size of each PM thread?

Also, are PM's archived somewhere? maybe that's why the table is so large.

Thanks for the help.
