Over on the Automattic Theme team blog, Michelle Langston has published a great primer on distributing themes whether they be free or commercially based. Besides the tips offered for distribution, the tutorial also covers a number of things all theme authors should consider doing before releasing there theme into the wild such as making sure it’s adaptable, adding a right to left style sheet and avoiding hard coding. I was happy to see that with regards to licensing, there wasn’t much fluff added. One other thing I noticed that theme authors should find helpful is a codex article that lists resources that are GPL-compatible such as Fonts and icon sets.
