I'm one of those slower posters; I can say 'I post once a week' but sometimes its longer. But that being said, if I know my partner is interested in the RP as well, I don't mind waiting. I have three long running RPs with two different partners that have been going on for years, and sometimes you gotta take a writing break. There have been times where it's been me waiting 2 or 3 months for a reply from them, or vice versa. I am fine with that. This is very much opposite of what I used to do (when I was younger and had less hobbies and less work hours), which is reply in a couple hours/less than a day. I know a former partner admitted that they sometimes very much disliked how fast I replied - they would be getting out their set of replies, and *bam* here's a new reply they have to their pile. It could be overwhelming to them. I... don't where I was going with this. I had a point when I started. ^^; I think its mostly communication and making sure you know what sort of things to expect from your partner, and being very clear on how often [i]you[/i] post.
