What Charmion said.

...if you've housed Catters from across the golbe on their travels or been housed by other catters, even in other lands. A Code of the Road that hasn't failed me yet.

...if lots of Mudcatters know the name of your house cat.

...if you're flat on your back in a hospital room and mail and cards and letters and e-mailmessages full of goodwill, karma and aid keep flooding in.

...if you wear two ID badges at the Getaway and other festivals.

...if people look a whole lot different than you imagined them from the printed page, and it doesn't even matter.

...if your singing repetoire includes at least one song learned from a Secret Santa package.

...if you remember the goodwill and comraderie in realtime of Mudchat in its glory years.

...if folks seek you out on Facebook and seem to share quite a few Catter aquaintences with you but you have to double check with friends because you never knew the real name that they're contacting you with.

...If you've had to referee or mediate at least one squabble among Mudfriends.

...if you know whose posts are worth checking out, even when quickly scanning a thread that's of no real interest to you otherwise.

...if you've made SINSULL's gift shopping list.

...if you've ever shared a few drinks with a Giant Squid.
