Hi - I'm never sure about commas after short (adverbial?) introductory clauses as listed below. Can anybody tell me if all 3 examples below actually require the comma, and what the basic rules concerning such instances are? Most grateful, Robboe.

- On 10 December, the company decided to blah blah blah
- Following comprehensive deliberations, the company decided to blah blah blah
- In particular, the comprehensive deliberations of 10 December lead the company to blah blah blah

We regret to inform you that the behaviour of commas is unpredicatable, uncontrollable, imaginative, innovating and creative. You should always bear that in mind if you hadn't already realised that. Emotion: smile That's why you like using them so much.
[:^)] , well, ok, then, hmm, comma, ... but if you were a comma, would you feel comfortable there? seriously, pls, I'd be grateful for a reply.

thanks, robboe
