iionly, we currently work on upgrade of approx. 15 plugins and 15 themes (they're already upgraded, they're being tested and we plan to release them soon, right now we wait for new shop platform we're mounting on vazco.eu to be ready). Unfortunately, vazco_mainpage is not in this bunch. It requires some significant modifications for Elgg 1.8, as the whole code which is used to implement HTML widgets and a few other widget types is gone. I would not want to release plugin with functionality lower than it's previous version (or version which implements hacks), that's why we delayed development of this one.
We plan to release new version of vazco_mainpage at some point, although it's hard to predict when.
ps. in case anyone would like to sponsor a plugin, we offer a discount for any future plugins released on vazco.eu after plugin earns amount for which it was funded, eg:
cost of plugin: 10
cost of development and sponsorship: 50
after 4 or more people buy a plugin, we can offer a discount worth of 40
This policy is valid for funding any plugins or upgrades.
I found this tutorial that is dated but still hold some cool info if you need to learn how things work as far as themes go. Easy to understand format written by Mayank Sharma
