Lost in a guild, how do you avoid this?

Blood Line looks like a really good guild, lots of activity, the 70's are working on getting everyone keyed for Kara and it seems the lower level folks are helping each other.

That's all well and good for me as I am used to working solo until I need help with an instance.

But, the question before us to day, is how do I not get lost in the guild. How do I work through the leveling process and not become just a member or a number? How do I become a positive addition to a guild and still have the ability to do what I want to do? I want to get into later instances and do end game stuff. I suspect I'll have plenty of time as I don't doubt I'll be 70 for an extended period of time prior to the new expansion coming out.
