How do you respond to two hash tags @ once on Twitter?

[James]

I'm new to twitter and I have to do a journalism homework assignment but I don't know how to respond to two hash tags per the homework assignment:
Homework on Tuesday, January 24: Honors (and extra credit for regular): Sign up for Twitter, post at least 10 tweets while listening to the State of the Union address, including at least three in which you respond to a classmate's tweets. Use the hashtags #sotu and #skylinejour for each and every tweet. (Yes, it eats up your 140 characters, but this way, we can find each other's tweets.)

It's very easy - twitter allows you to mention to one / two / 3 / 4 / etc users. btw, @ - mean mention.This is hashtag - # . in one twitt you can use as much as hash tags and mentions you like (unless it's up to 140 characters of course...)

Finally, if you're new to twitter - follow me...
