While rewritting messages caching code I decided to store message flags in one field as a binary sum. Of course the main idea is to get some unification and better performance. The bad side of this solution is that we can store this way only known flags defined in the code.
So my question is, do you know/use other flags than listed below (\ and $ chars removed)?
