The portal mod has now been updated to 1.8.1 (Buildcraft has been, too, in case you missed it), and few other news I can give you all. Anyway, as usual, the port hasn't been perfect, and the mod's author cannot give it all the time it needs, so there are some bugs. Fortunately, a "no hunger" option has been made, but as always I suggest to wait until things settle up (hopefully in 1.9).
Of course, if Notch keeps the timetable, we've got about a month and a half before the full release of the game, so we'll have a few weeks of 1.9 with all the mods.
In the meantime, go to visit Paulosoaresjr's youtube channel, since he's making some nice videos for farms.
Personally, I'd like to see some more love to the minecart system, for Buildcraft's builders and fillers to be able to place seeds and rails, and of course some more hours on the day XD.
So, until further notice I think I'll slow the posting speed to one post per week, and that I'll devote the (few) hours I play Minecraft to work on an old project I had to put on ice, a small Portal map. With turrents, because we all love them. And cake, of course.
