What kind of advice are you looking for?
If you want general advice about which category to submit your site suggestion to, if you describe the type of site it is, without giving the url, one of us can probably steer you in the right direction.
If you want advice about writing an ODP compliant description for the submission of your site suggestion, we can probably help with that.
If you want help with the design or content on your site, then you should try a webmaster forum, we don't do that here.
If you want us to go look at your site and review it, we won't, that would be giving you preferential treatment over other sites that have also been suggested.
