My friend just joined up on beastkeeper using his phone. However, he texted me that he can't go through the tutorial because beastkeeper isn't working with the phone. If he used my laptop to get through it, would my game or his game be affected? Would we be banned?

Your friend will not be banned for using your laptop. Make sure you log off before your friend logs in (and that he logs out after!). If you are worried you may post in our "shared IP thread" http://beastkeeper.com/thread/270. 

We will not ban you guys for multi-accounting unless there is one-sided trade between you and your friend (like if they send you everything, or vice versa). You can still trade, just make sure that it does not look like one account was a "mule" and everything was being funneled into another account. Basically if we were to look at your trade logs (which we can do) does it look like one person's account is getting all of the goodes? 

That being said- The site works on most mobile devices, in fact, Angel updated it and the site works on my Windows phone now. There are a few features that still require a browser (such as exploer and the arena). 

I'm happy to answer more questions :)

The odd thing is that I can't click in the message field when I'm trying to reply to a message -- all the other fields work fine. Stranger things have happened at sea, I guess...

Are you using the rich text editor, or the html version. The rich text editor is so-so on my phone. I can only type as much as what fits in the box and then I can't scroll up to see what I've typed (or down).

The html version is simpler (you need to input your own tags to format). Also, on my computer my spell checks works there (which for my dyslexic mind is great). I can scroll with this.

You can change your preference in your profile's settings.

What kind of device are you on?
