In case you haven't heard, the minnowsupport bot malfunctioned yesterday. The system has been rebooted but you may find that the bot has forgotten you have been registered, throwing out a 'This feature is restricted to Registered Members' or something like that.
Before you attempt to initiate an $upvote command, pop into registration on PALnet and use the $register command again (remember to use your Steemit username without the @. This should clear things up for you. If not get in touch with one of the moderators.
Thanks
