I need a little help with this...

I was thinking for my 2 years Wattpad Annieversary, I had four ideas. Please tell me what you think you would prefer.

1. A Q&A

2. A face reveal I will keep up for only 24 hours with a snap chat filter covering up most of my face...

3. When I follow anybody who comments on a post or something

4. A contest

Please tell me what you'd prefer before August 17!! (Which is the annieverary)
