I've got some spare time to spend on SEO on my site. I've already don'e the basics, all on-site SEO. Some backlink building etc. Last night I made four linkwheels. One with about 30 sites. And three smaller ones with about 5-10 sites each, all wheels for my single website. And today I submitted it to around 150 directories. So what should I do tonight? I don't really like the medial repetitive tasks. And I don't have much money to hire people or buy site lists.
You are doing good job by doing forum posting. If you can write comments to blog using anchor text in the PR pages you can get authorative backlinks.
