This is a dedicated board to designing SP blocks. Show off the custom blocks you've made, package them up as a sub-mod for SP and distribute here, ask for support on certain custom blocks, and so on.
This is NOT the place for general Simple Portal support. If you're looking for support with the default blocks or the portal in general, check out the Support Board (http://simpleportal.devira.info/index.php?board=11.0).
I should also note that; as you can guess, we only code a single mod here and do not use all the mods in the SMF Mod Site. Although all SimplePortal Team members are specialized in their areas, it is certainly not easier for them to code block for a mod they have never used nor downloaded in their life. So, if you are looking for a block code related to a specific mod, the first thing you should do is to request it from the author of the other mod.
