4 of 5 Added apostrophes, got rid of "who"

How do you code without offending?

What I mean by that is, how do you go about developing on a code base you share with developers who have been working on it for years and are very familiar with it?

I don't want to step on anyones toes, but I get not so subtle complaints about the way I do things, whether it be how I whitespace my code, or how frequently I checkin to SVN (too often). So while I can change those things easily -- I want to be a better team developer in general.

I'm not sure what to do, other than ask, but maybe you guys have some thoughts I could put to practice.

UPDATE

There isn't any style guide to speak of -- it's just people aren't used to sharing the codebase. Everyone has their own little siloed code-world.

This is a perl shop, but I'm sure these apply to any language
