Welcome to Fluther.

Yep. No apologies. And welcome to the ocean!

Welcome to Fluther.

We don’ need no steenkeen’ apologies.

Goodness no, but it is lovely that you care. Welcome to Fluther. I hope you will enjoy being part of our community.

Right here; this is the official n00b thread.

No apologies need be given.

The lurve score right next to your name is low enough that anybody who reads your name will also see that score and instantly know you are new to Fluther, and thus still learning how things work here. We here at Fluther are a generally friendly and forgiving lot, and we remember what it was like to be a n00b.

Oh, I almost forgot… Welcome :)

Welcome to Fluther. If you mess up, your answer will be moderated. You can then ask the mods for clarification if you don’t understand why it was removed. And don’t worry, it has happened to all of us.

Welcome, @DaphneT! I’m the community manager here, so if you have any questions or need any help, feel free to ask me. :)

Pfffff! No apologies necessary. If you step out of line, Agustlan will be happy to write you a note detailing your sins, if possible contracting your name in a derogatory fashion.

Welcome to Fluther! We don’t apologize for nothing around here! So, you’ll be fine. But if anyone does yell at you for your n00b questions, let Auggie know and she’ll take out her whip on their behind.

No apologies necessary, just take a look at the guidelines and give it a go.

Welcome to the insane asylum Fluther!
