→Account creation: why and how?
We strive for maximal accuracy, but a lot of content has not been proofread carefully, and the complexity and quantity of content make errors inevitable.
If you think you've found an error, report it in this short [http://www.surveymonkey.com/s/
groupprops-error-report external anonymous survey]. You can also view a log of some past errors (that stayed on the site for a nontrivial length of time before being fixed) at the [[Groupprops:Error log|error log page]].
If you create a login, you can track the error log page and hence be notified when an error (satisfying some criteria) is corrected on the site.
The site is ''mostly'' error-free. Generally, errors are unlikely to be present in the overall flow and gist but may exist in small details such as missing elements from lists, typographical errors in numbers (a 7 instead of an 8), poorly rendered math, etc.
If you're a newcomer to the subject, scrolling through the pages should give you a fairly good idea of the material, and the minor errors probably won't affect you at all since they'll be in details you will not pay much attention to anyway. If you're experienced in the subject, the errors will probably be things you will confidently catch if you notice them, and are unlikely to mislead you.
In most cases, we strive to provide clear explanations and justifications for all statements. For statements that lack justifications, take with a pinch of salt. For any statement that seems fishy, click through on links to further elaboration and see if that further elaboration checks it out. In many cases, we provide implementations in GAP to cross-check or verify statements.
If you only want to surf the site content, you do ''not'' need to create a login. All parts of the site, as of now, are visible to users without logins.
