user5486: The majority of pools I see that they use a period such that:
username.workername
others use:
username_workename
I see that it definitely is not interchangeable.  How come some pools use underscore (such as bitminter and btcguild)  and others use a period (like gigahash.io)?

user13751: These are just arbitrary rules. Made by the pool admin. Really doesn't matter.
