Where to find elementary (?) help?

[Arjen]

Hi,
Before I start posting too elementary questions, first a meta-question. I have started drawing some very simple diagrams. Very soon, I bounce at drawing issues (activations that are intersected when I move a message down, impossible to draw messages downward in communication diagram, etc.).
My hunch is that there are solutions to the things I want, but I just can't find them. Where to look? Or is it ok to post some examples here?

Thanks
Arjen

If it's above the level "can you pls explain UML" (IOW anything specific in contrast to not specific) it's okay to ask any question here
