@Angelic Neko Sounds good to me I would go into more detail on what exactly it entails e.g. a step by step example or such.
Summer Art Bonanza
All forms of art media including drawn, crafted, writing, gfx, cosplay, photography
A little like the "make something" thread I run. Each week have a new theme relating to a Summer thing and encourage people to create whatever they want to and make a mass thread where everyone submits their works for each theme and keep it running through August to early September.
Could also try to promote this in other sections and find people in the intro threads to try and direct them to take part for fun and getting to know people.
