Bitem Challenged

A newbie confused about bitems.

A bitem is a big mystery
Confusing for  newbies like me
If you don’t know how a bitem works
You may lose a lot of perks

Bitem challenged I may be
But I can still write poetry
Some of it is pretty good
When I’m in the writing mood

If you by chance are challenged too
By all this confusing bitem pooh
Drop a line and say hello
I’ll listen to your tale of woe.
