I remember my first days of MMO's - very daunting indeed. My advice to you is to play the game first, get used to its mechanics and see what it is about the game that you enjoy. Is it questing / leveling up, crafting, Role play, exploration, End-of-Game contenting (raiding)...this will ultimately dictate the type of guild to join. I've been a member of a few Kinships (Guilds in Lord of the Rings Online) and each time the experience has been different. Some are friendly and mature - just generally hang out, helping each other out. Others are solely interested in being the first to do things and are very "End-of-Game" orientated. By that I mean they arrange times to meet to attempt 24 player group quests that can last up to 2-3 hours.

It won't limit your play experience at all, if anything it'll enhance it. They give me a sense of "community". I'd deffo call myself a solo player but sometimes help is required and it's easier to find help if you're in a guild. I've also found that PuGs (Pick Up Groups - random players grouping together) don't really work as it's difficult to get strangers to follow instructions...it can lead to arguments and ultimately the downfall of the quest and that's no fun for anyone!!

You can continue to play by yourself, leveling your character and just generally exploring. Being in a guild will give you a guild chat channel so you can remain in contact with other members that are online at the same time as you. There will normally be a website to accompany a guild - this is where membership, events and general tom-foolery takes place when off-line.
It's purely down to player preference Gem, I've deffo found being in a guild a positive thing - but I guess I got lucky with my LotRo kinship as it's full of like minded individuals.
