I was wondering how people (and even Machu) made the text smaller. Any help?

Between a set of words, input this symbol: ~
That way, you can type smaller.
For example, _{I'm typing really small}.
Hope that helps.

Look in that one text formatting topic. Search for it in the search bar up top.

You have to use the ^ symbol (Shift + 6) in-between a string of words.
Example: ^{Small words are small.}

Does '^' work?!

_{: ~Small}
^{: ^Small}

Okay, it does.

Read through this, I know you got your answer but there's lots of other info in there. (I don't think making text small is there, incidently).
~ makes text small at the bottom. _hello
^ makes text small at the top. ^hello

Starkiller's link to the helpful tips for formatting messages topic aside, if you see someone do something on the forums and you're curious about how they did it, if you quote them, you'll be able to see the bare code that produces that particular effect. :3

Wow, quote of the year!!! I'm not sure what to think of it, but that's why it's so good.

_{you got a problem there buddy ;P}

Yeah Machu posting; we're all amazed, really.

One small step for Man, one giant leap for Machu.

Lolcats just make everything better, don't they?

They sure do. Everytime I go looking for one, I lose ten minutes whilst I smile at cats that can haz...

It's not necessary, but, if you want, here's a way you can type even smaller: :3
Just input either ~ or ^, then use the brackets with the word "sub", and voila.
_{Hooray for tiny text! Hope I wasn't mean. =(}

_{StarBoy just knows all the tricks. Impressive. not}

_{normal tiny text}
~_{Starboy tiny text~}

Is there a way to make text bigger?
_{Hooray for people with bad eyesight that can't read this!}

Don't mind me, I'm just testing...

@zez - there is a way to make text bigger. Before and after a set of words, insert four = signs (two in the front, and two in the back). That way, the text will get bigger.

Example

_me

I'm
_{shrinking,
no!!!!!!}

Just testing the bigger text.

And it's awesome.
