I'm sure you have noticed that the Graphene theme is quite in active development, with updates coming almost every week!
What you might not have noticed though, is that usually a major update (e.g. from 1.0.7 to 1.0.8) is followed immediately with an maintenance update (e.g. 1.0.8 to 126.96.36.199) just hours after the major update.
The reason for this is that it is quite impossible for me to test for all the fixes and functionality on my test WP installation and catch all the bugs that may arise from the new bugfixes and feature implementation, especially now that the theme has reached almost 30,000 downloads. Thus, some critical bug slipped by sometimes, and it's lucky enough for me to catch them just after release, and release another immediate maintenance update before the main bulk of the theme's users update the theme.
I am therefore asking for your help to be beta testers for future versions of the theme, before I release it to the public.
If you're interested, just reply to this post and I'll add your email address to the mailing list and inform you when a new beta is available for download.
