If you care about an RP, you will read the preceding posts. Full stop.

Depends of you have time to read all those posts. 100 long posts is alot to read when they 500 words + that's. 50,000 words, or 5 full college dosertation essays at BA level. 
Sometimes q skim read and asking for a quick version and time line of events roughly helps alot to allow easier joining. 

Ie a general outline of events, charceters and where it roughly going.
