Other Confused old newbie here.

So, I'm 63 and not real social as in I don't do a lot of commenting or posting I just read the forum posts and classifieds. I have only been a member of the site for a few weeks now and as I said, I haven't really posted anything. I found a bottle for an FX airgun which I have been looking for since I have a Panthera Hunter and wanted to ask a few questions and possibly purchase it. However I get a notification that I must have a minimum of 10 posts and a minimum of 10 days of activity. I'm not really sure what that means? 10 posts of things for sale? 10 posts of just discussion? I have no idea what "posts" I need to be working towards not that the bottle I found won't likely be sold by then anyway. And 10 days of activity? Does that mean just browsing? Being a member of? I again am not quite sure what it is I need to do. Like I said I'm 63 and not real active on the internet so I'm kind of dumb when it comes to all this stuff. So any guidance as to what it is I need to do would be appreciated. I also have a friend who is worse than me, he doesn't have the internet but saw some things on here when I was looking at the classifieds and he had interest but I told him I would need to figure out what it is I need to do before I can help him out. So, Thank you for any help! Larry

I like it so far. It fills my small Ninja tank and all my guns and it's fairly quiet. I have another cheaper compressor that will only fill to 350 bar that I will use if I go to the range. I can hook it to my battery and run it off that.
Hmm? Mine hooks up to my trucks battery as well, it sure looked the same as mine. I only fill my guns as well, max size for me is 480cc.
