Posting Spoilers and Collapse Tags

I have a suggestion: adding collapse tags to projecteuler.chat, because apparently they aren't a thing right now.

Also, is it OK to post spoilers as long as you hide them with hide tags or collapse tags (when they get added if they get added)?

Re: Discrete Math Problem

Proof: It can be seen that $x^2+2x+1$ is even, as given in the problem. Therefore, $x^2+2x$ is odd, since an even number minus $1$ is odd. Then, we know that any integer multiplied by $2$ will be even, and an odd number minus an even number will be odd. Therefore, $x^2$ is odd. Since squares of odd ...

Uhhhhhhhhhhh........

So there is this Project Euler user named Jeetsagar, who has solved 54 problems, all of them 5 percenters. So, I scroll down to the posts' section, and there is a permanent post for problem 349. What's funny, is that the user hadn't solved problem 349 yet. What is going on with that user? Is it beca...

Re: How to get a permanent post?

FYI I know two posts that have 4 or more kudos that aren't permanent. One is on problem 116, and the other is on the pandigital multiples one. There may be many more, so you might want to check for some. P.S. the posts I mentioned are soon to be deleted.

Re: Problem 504

I had the same question :). Maybe the admins could edit the problem and define what "strictly contains" means on the problem?

Problem 571

A n-super-pandigital number is a number that is simultaneously pandigital in all bases from 2 to n inclusively. However, I don't know if a number can be a pandigital in base i if it has a leading zero. Can a number in base i have a leading zero? EDIT: I'm thinking that leading zeroes aren't allowed....

Re: Problem 585

I am attempting to verify a conjecture via brute-force to help me solve this problem, I have no alternate ways of verifying this yet. So, can someone confirm that F(2000) = [ number removed ] There is no number there (because it has been censored), so I can't really help you, but I would suggest to...
