One question - any advise how to deal with people who "borrow" your presentation, in other words, they interrupt, and start explaining the concepts for you.
Luckily I haven't encountered this often. And on at least one or two occasions, when something like this has happened, it's actually been a positive in that the person was adding useful information that complemented what I was already saying. In that case, I don't mind letting them go on for a minute or two.
That said, at some point you have to take back over if you're going to get through your material. It's not in my nature to generally be rude or brusque with people, but sometimes you may have to force the issue a little. You might choose to intentionally wear a wristwatch just so you can do the gambit of "conspicuously look at your watch, and then interrupt and say something like 'OK, in the interest of time we need to get back to the main thread now. Perhaps we can have a follow-up conversation later on XYZ.'"
A common interjection as well is something like "This is good stuff, but we're getting a bit off-topic. If you want to talk about that in more detail, grab me after the talk and we can chat." Something like that.
