I’ve create my first plugin. It’s a wordpress newsletter plugin. it’s a good idea to create your own plugin, because you can have many traffic from there if your plugin is usefull. If you don’t have the ability but only the idea, you can hire other people to write you one (maybe me).
I’ve submitted it to wordpress and receive an email about SVN repository. The problem is I don’t know how to upload the files to there. WordPress did not give sufficient tutorial about this. They assume that every body knows this things. After browsing more than one hour, I finally found this great tutorial. Basically you need to download first Tortoise SVN
