Two weeks is what I had in mind for the upper limit of post frequency. After that the character will be marked as inactive. But, as you can come back anytime, it's not really a big deal. 

This perception of time is just a GM-thing. I'm sure you can relate. A week feels like a month when someone hasn't posted.

I'll update the first post with a 'rules' section.

Edit-

[sub][color=#6A5B7E]◆ Rules[/color][/sub]
➡ Be courteous to each other, compromise instead of complain, and communicate with me no matter how trivial the matter.

➡ Summarize posts considerably longer than a thousand words. This can be done in a hider at the end of the post.

➡ Two weeks is the upper limit for post frequency. A character/player will be marked as inactive after that time.

➡ Post updates about yourself in the out-of-character thread whenever you can. If you have nothing to say, the magic words are: [i]The Wicked Witch of the West went her own way[/i].
