Yes and no. As with any downloading, the source may be inherently evil. For instance, satan.com will probably not be the best place to download skins. But yes, it is worth it if you don't really like making them. And who does? Does anyone dream all night of making skins and then get fired at work because all they do is make skins on their computer? If so, good for you, market that and sell skins for a dime a dozen.
Use the import editor to import into the map. It has to be imported over the old models path.
Unless they tell you or you can extract from the .mpq files and open them then you need to guess.
Most skin files are in:
Textures\UnitName.blp
Race\UnitName\UnitName.blp
So Blood Mage is Textures\HeroBloodMage.blp and the Footman should be Human\Footman\Footman.blp(actually I don't think it is but thats an example).
Some tricky ones are the Warden(Textures\IronRaven.blp) and the Night Elf Archer(Textures\Ranger.blp).
I am working on getting access to the old news portal under a different URL for those that would rather use that for news before we get a different news view.
It is OK though for the main page to open up on the forum in the view it was before. As long as the portal has its own URL so it can be viewed that way I do want to try it as a regular forum view for a while
I switched it to a "Standard" article forum. This will show the thread list like normal, but the threads themselves will have the first post set up above the rest of the "comments"
I would like to see it again like Ghan had it the first time with pagination though - without the pagination that view will not work but with pagination it just might...
