If you've
suggested your site to us, then that's all you need to do. The suggestion is just that, a suggestion, which we intend to look at in due course. We're trying to build a directory not process a load of links submitted by the public. The editing is also done entirely by volunteers. Therefore we don't and can't provide any guarentees as to when a suggested site will be reviewed and potentially listed. (Indeed looking at the suggested sites isn't the only way we can build the directory, and adding new links isn't the only editing activity that needs to be done.)
I'm afraid that two months isn't a particularly long time to wait between a suggestion and a listing, but until a site suggestion is reviewed it stays waiting in our database, so there's really no need to suggest it again.
