Building on the Platform
Written by Elin Waring
If you missed the happy twittering, last week at the Joomla! Day Chicago there was a spontaneous gathering of developers--yes, that includes you Ryan Ozimek--shut up in a room having a great time writing platform applications. As Nicholas Dionysopoulos said to me “I guess that will put an end to the incessant "why did we have to separate the platform from the CMS" question. To be honest, I had the same question myself, until Joomla!

We released Grid2 back in June 2010, as follow up to the original Grid template and it's been a massively popular template with photographers, artists and well pretty much anyone who liked the display of the grid layout on the front page.

Written by Anthony Olsen

It turned out to be one of those things that took 20 minutes to figure out and a little bit of swearing at the screen but was ultimately solved in two simple steps.

Spam Registration in Joomla / Virtuemart
Written by Thomas Kahl
During the last days we received a huge number of new users. Normally, we are happy about this - but these users were no "real" users. We received about 50 new registered users per hour, which was really annoying, because they obviously were no new customers. They were registered by (i guess) script kiddies. I really don't like "captchas", because the only annoy the real user. So we had to find another way. If you also have this kind of "users" and your shop only needs the registration during the checkout (like vm-expert.com), you may find the following solution helpful (though it needs a hack):
