What is everyone SAFELY using now-a-days for delay timers and such?

Sorry about the slightly misleading title, but I wanted to grab as much attention as I could. I haven't been around much in the past few years, but I'm getting back into the Seo life.

Basically the question is this: What is everyone SAFELY using now-a-days for delay timers and such? I am willing to edit and use this post as the new 'bible' for Mass Planner and Followliker if there's enough contribution to the thread.

So yeah, feel free to add information and opinions. Anything worth…
