You don't need to register a namespace before uploading a new module. As far as I can tell, the only purpose of registering a namespace is to prevent others from uploading modules into subnamespaces (for example PDL::SomeMatrixFunc::ReallyFast). I think it doesn't even prevent uploading, search.cpan.org just shows the "not an official upload" warning in red letters. I have uploaded about 9 distributions to CPAN, and haven't registered a single namespace for any of them. Perl 6 - the future is here, just unevenly distributed	[reply]

There are only two real reasons to register a namespace. One is to reserve the namespace without having to ever upload a distribution to CPAN. Simply being the first to upload to a namespace performs a first-come registration (See 1). Note that either method of registering does not reserve the namespaces below it. So registering or uploading Foo, does not reserve Foo::Bar. The only other reason to register a namespace is to be included in the topic list shown on the search.cpan.org homepage. But that list is barely useable and most people search nowadays and don't bother to browse. I personally hate reserving without uploading. When I searched CPAN to see if a namespace was in use before I uploaded my own distribution, nothing showed up. But when I uploaded, mine was listed as unauthorized because somebody years ago had pre-registered it and never made use of it. The author also refused a request to assign it to me, claiming he one day plans to make use of it. There are many claimed, but unused namespaces like that. 1: https://pause.perl.org/pause/authenquery?ACTION=peek_perms	[reply]

Please don't use square brackets in the manner above. If your taste in formatting footnote pointers runs to [...] use `[...]` because the local variant of HTML uses square brackets the way standard HTML uses `<a href=...</a>`. That means you could also have created the link thusly: `[https://pause.perl.org/pause/authenquery?ACTION=peek_perms]` which would display the url, linkified; or `[https://pause.perl.org/pause/authenquery?ACTION=peek_perms\|<super>1</super>1]` which would render as ^1. -- a superscripted 1 -- and thus would serve as a link to PAUSE as well as a pointer to a footnote... probably not what you want, here, but useful in some cases.

There's very little reason to register module namespaces these days. Most people don't. TOBYINK (me) - 127 distributions; 7 are registered RJBS - 255 distributions; 2 are registered ADAMK - 245 distributions; none are registered STEVAN (of Moose fame) - 73 distributions; none are registered FLORA (famously everywhere) - 201 distributions; 6 are registered `perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'`	[reply]

Don't bother registering, it's an obsolete mathom left over from the very early days of the CPAN before there were services like search.cpan and metacpan and tools like CPAN.pm, and is now completely irrelevant.	[reply]
