@Mars: thanks for the explanation! (I've found very interesting how '[+special:alias]' work, especially on how we can combine macro code with an alias (an alias that works almost the same as a 'variable'). It surely gives endless possibilities and makes the code more easy to handle.
@Danny: I've tested the new Throwback7.tpl and this is getting better and better (that gradient background looks great). By the way, I don't see any more enhancements available without slowing down the server, so, it's done for me, at least for now.
Cheers,
Leo.-
