Lobo feel free to delete this post once read but before we get to many tips and tricks added to the thread it might be helpful to establish some ground rules in your opening post.  Make the distinction that this thread is for a Tip/Trick/Hint and not a tutorial like "How to model a rocketship".  I would also suggest that in the first line of any new post that the nature of the tip is identified first and then the tips description.  This would make it much easier to scan through once the thread starts to roll over to many pages.

For example the opening first line of a post could be:

Modeling - Using the Bridge Tool  

Particles - Gravity Settings 

Nodes - Organising the Node Tree

My thoughts for your consideration.
