@minnowbooster still has delegated sp leases now but you need to order it for 8+ weeks or you will not get it. Too many people are trying for the 4 weeks. I got 12 weeks for my son and it came in an hour. I tried to get 4 weeks to give to a friend at the same time and did not get it.

If you are looking for places to post, @kalemandra just did posts of challenges and contests to enter. There are so many that she did two posts. This is one of them, and it leads to the other:

I advise picking several challenges or contests and posting to them regularly, This is what I do and it helps a lot. I too have difficulty posting, but I know I am entering certain challenges on certain days. Others are available anytime.

@mariannewest does the daily #freewrite and that is a really good starter challenge. It's quick, has good people in it, and will teach you skills.

Good luck! this is the place to be!
