OpenGL does not have any functionality for particle effects, and TBGL also not at the moment. I was tempted to add them multiple times in the past, but the problem is that particles are very general thing.
I did lot of examples on particles in pre-entity era, but I think I could help you with this and create something using entities. What do you need the particles for (what kind of effect: smoke, fire, ...?), in what amounts (few, thousands, ...)?
