This isn't a rude question at all!
Well the point of starting it is that last year I felt like the only kind of news I was hearing was something bad (like on the news and Internet) and a lot of people I knew were at points in their lives (including myself at one point too actually) where they needed some encouragement to just keep going. When I couldn't seem to see any positivity at all, especially with the new year coming around I wanted to make something that would spread positivity and being someone that makes comics it seemed like the only way to get something like that through.
After I reached out to chibichu she felt similarly. and tapastic being the amazingly nice community it is, we just knew that people would also feel similarly.
But i guess that doesnt really answer your question so im sorry for babbling. If you mean purpose specifically, its to gather artists and spread messages that we (the artists) feel like others need or that we feel like should be expressed like reminding people that they matter for example. People do post positive messages occasionally in their own comics but having it all collected in one along with other artists who want to spread the message but cant because of lack of subscribers can share them too. Think of it as a collection of positivity. All we hope to achieve is that there are some people that will be affected when reading it making atleast their day a little bit better:)
sorry for the huge explanation. I didnt mean to blab but I just want to make sure i answered your question. Im still not sure if i did it properly lol but i hope so.
