Creating Community subsites

I tried to create a community on my brand new SharePoint 2013 server.

First of all, the familiar Site Actions->New Site has been moved. You now have to open the gear menu, select View Site Content, then click new subsite. According to some blogs, there should be a Community template, but that does not appear on my list.

Recalling that a subweb can be converted to a community via activating the Community Site Feature, I just created a Blank Site and tried to activate the feature. This is when I ran into the following errors:

The Site scoped feature being activated has a dependency on hidden Site scoped feature 'FeatureDefinition/4326e7fc-f35a-4b0f-927c-36264b0a4cf0' (ID: '4326e7fc-f35a-4b0f-927c-36264b0a4cf0'). Hidden features cannot be auto-activated across scopes. There may be one or more visible Site scoped features that auto-activate the dependent hidden feature.

Curious about what these are? I ran the following Powershell

@("4326e7fc-f35a-4b0f-927c-36264b0a4cf0", "915c240e-a6cc-49b8-8b2c-0bff8b553ed3", "d32700c7-9ec5-45e6-9c89-ea703efca1df", "947afd14-0ea1-46c6-be97-dea1bf6f5bae", "c6a92dbf-6441-4b8b-882f-8d97cb12c83a") | ForEach-Object {Get-SPFeature $_}

and got the following:

DisplayName                    Id                                       CompatibilityLevel   Scope

-----------                    --                                       ------------------   -----

AbuseReportsList               c6a92dbf-6441-4b8b-882f-8d97cb12c83a     15                   Web

Is there a feature that will activate all these as well? Searching around the internet, I did not find any so I figured why not try just activating the 2 site scoped ones using the following Powershell:

$site=Get-SPSite https://somesiteurl
$feature=Get-SPFeature "4326e7fc-f35a-4b0f-927c-36264b0a4cf0"
Enable-SPFeature -Identity $feature -Url $site.Url

$feature=Get-SPFeature " 915c240e-a6cc-49b8-8b2c-0bff8b553ed3 "

Enable-SPFeature -Identity $feature -Url $site.Url

I then went back to the Blank site and was able to activate the Community Site Feature.

I also tried new subsite and, lo and behold, the Community template is now there.

I am sure that someone will soon document how this should actually be done and that this will also be fixed in RTM, but until then, this works for me.
